TLDR
The confinement of light within a hollow core (a large air hole) in a silica-air photonic crystal fiber is demonstrated and certain wavelength bands are confined and guided down the fiber.Abstract:
The confinement of light within a hollow core (a large air hole) in a silica-air photonic crystal fiber is demonstrated Only certain wavelength bands are confined and guided down the fiber, each band corresponding to the presence of a full two-dimensional band gap in the photonic crystal cladding Single-mode vacuum waveguides have a multitude of potential applications from ultrahigh-power transmission to the guiding of cold atomsread more

Analytical evaluation of chromatic dispersion in photonic crystal fibers
TL;DR: A two-dimensional modal approach for the evaluation, in an analytical manner, of chromatic dispersion in any kind of optical fiber that combines an iterative Fourier technique to compute the propagation constant at any fixed wavelength and an analytical procedure to calculate its derivatives.

Fibre optical sensor for C2H2 gas using gas-filled photonic bandgap fibre reference cell
TL;DR: In this article, the first optical fiber correlation spectroscopy gas sensor using no lenses other than in the measurement gas cell was presented, where a 1m length of photonic bandgap fiber (PBGF) was filled with acetylene at atmospheric pressure, then fusion spliced to standard, solid core, singlemode SMF-28 fiber to form a compact, coilable, reference cell without the need for any lenses or bulk optics.

An air-core photonic crystal fiber based plasmonic sensor for high refractive index sensing
TL;DR: In this paper, the analyte is placed to the core of the photonic crystal fiber (PCF) through a vertical side opening channel and is able to detect analyte refractive index (RI) higher than that of the PCF background.

All-silica single-mode optical fiber with photonic crystal cladding
